Is this normal

So I’m a first time mom & I’m 19 years old. My boyfriend and I would have sex during my pregnancy up until I turned 4 months . It just became really painful and I couldn’t stand him trying to go in because it just hurt so much! It’s like if I had swollen shut. So I hadn’t had sex since then . I gave birth and everything and my baby is now 3 months old but I do not have the urge to have sex . I don’t feel like it and I don’t get turned on or anything. I feel really “eh” about sex . So I haven’t had sex in 8 months . But I haven’t felt the need to and my boyfriend hasn’t pressured me into anything either which is nice. But I have NO sex drive .. is that normal??
